Dr. Williams Serves His Patients, His Family, & Others Around the World

Dr. Gregory A. Williams has dedicated his life to sharing his time and talents with his family, the patients at his thriving dental practice, and others around the world through his humanitarian efforts.

When it comes to his patients, Dr. Williams is committed to providing compassionate, comprehensive dental care. Dr. Williams began his dental practice in the Tigard/King City area in 1998 after graduating from Oregon Health & Science University with high honors.

He continues a commitment of lifelong learning through his membership in professional associations, including:

As a top dentist in Tigard, Dr. Williams also serves as a Master with the Academy of General Dentistry, which is an honor fewer than 1% of dentists achieve. He is also a Fellow with the International Congress of Oral Implantologists, a Diplomate with the American Board of Oral Implantology/Implant Dentistry (ABOI/ID), and a Fellow in the American Academy of Implant Dentistry. As an adjunct clinical instructor and student mentor at OHSU, Dr. Williams works with and instructs dental students on a regular basis.

Dr. Williams has also developed a passion for humanitarian work at home and abroad. For years, he hosted one of the largest clinics in Washington County during the national Give Kids A Smile campaign. Since 2005, Dr. Williams has traveled annually to remote areas of the world including most of Central America, Peru, Ecuador, Samoa, India, and Nepal providing dentistry to thousands of people, many of whom have never seen a dentist.

Shortly after one of these trips was when he and Dr. Scott Dyer co-founded Wide Open Humanitarian, Inc. Established in 2007, this not-for-profit organization brings dental relief to the poorest of the poor throughout the world, instructs the dentists in these remote areas regarding practical techniques, and helps pave the way for future organizations to set up ongoing clinics.

Dr. Williams has been married to his lovely wife, Michelle, for over 30 years. Together they are raising the youngest of their seven children and recently welcomed their fourth grandchild. They can often be found coaching youth soccer or basketball, as well as cheering at their children's sporting and musical events. They enjoy time as a family through activities such as swimming, hiking, backpacking, cycling, and working or playing in the yard together.

Dr. Williams' adventurous spirit is reflected not only through what he does for others but also how he chooses to enjoy his time away. Dr. Williams has participated in several Sprint, Olympic, half Ironman, and full Ironman distance triathlons. He also works with young men ages 16-18 in church, taking them on regular high adventure activities.

This kind of passion and dedication guides Dr. Williams through how best to care for his family, his patients, his local community, and those around the world.

I had a great experience at this dental office. The visit went very well, and both the doctor and the staff were incredibly kind and welcoming. Since I don't drive myself, I really appreciated how helpful the front desk was in finding the most convenient appointment times for my schedule. They were also so eager to assist me in creating a treatment plan that fits my smile and what I’m hoping to achieve from my future visits. Highly recommend!

His office staff and the team of dental assistants are exceptional. Trust me...if there was any reason to distrust this dentist, I would have found it. Instead, I found a professional that became both my Doctor and my friend. Charles Wilkinson

Dr. Williams and his entire team are great. They knew I had anxiety and reservations about needing an implant. He took the time to thoroughly explain the procedure and recovery. Every single person in his office are kind and professional. I had a full mouth exam at my most recent appointment and discovered I need extensive teeth scaling and cleaning on teeth that were done 2 months ago at another Dentist as well as a crown and some resin tooth service repairs. I'm confident everything I need Dental wise will be done properly this time. I can't recommend this practice enough.

Dr. Williams and staff are top notch. They don't take shortcuts and make sure the finished product is done to perfection. I'm very pleased with the way I've been treated and would definitely recommend them for implant procedures.

Everyone was kind, understanding & considerate. I was there to get scans of my whole mouth, but got nauseated on the way in the door. I broke out the alcohol pad & Ginger Chews to combat. This gal was so good she was able to do the scans in like 8 minutes with Ginger chews still in my mouth. Dr. Williams came to the lobby after I was done and just chatted with me. What a personable guy he is😉

Everyone here is so friendly and informative! I’ve battled with cavities my entire adult life and finally found out a few reasons why, not for lack of good hygiene, just some small things that add up! Wish I would have known this 40yrs ago!! Dr. Williams is going to be redoing my whole mouth...

Wow, just wow! Dr. Williams and his entire team are amazing! From the moment I walked in for an evaluation to the time I left after my final visit EVERYONE was so nice, caring and helpful. I had terrible teeth - missing teeth and an ugly old bridge, baby teeth (at 57!) that hadn't fallen out - my mouth was a mess! The Dr. gave me a great plan to make all the top visible teeth look uniform and natural. I needed to whiten my bottom teeth. We went with several crowns, two implants and a bridge. They helped me whiten my bottom teeth and sent me to their lab where Mookie helped me custom match the top teeth to my bottom teeth. We had to go through a couple of trial runs before we got the PERFECT teeth. Everyone on their team was awesome about giving input on how everything looked. If “we” as a group didn’t think they were perfect they’d go back to the lab and explain the changes we needed. I felt bad not loving the first set, but they kept reassuring me that THEY wanted my teeth as perfect as much as I did. They weren’t going to be happy unless I was happy. After not smiling for more than a decade or more it feels incredible to smile and feel pretty and confident. I’m beyond thrilled that I chose Dr. Williams and his phenomenal team. I highly recommend them. They make you feel welcome and special. I loved everyone there and I know you will, too! THANK YOU DR. WILLIAMS & TEAM! I will be forever grateful to you all.
